Green Lacewing Preferred Food: aphids, mealybugs, spider mites, leafhopper nymphs, moth eggs, scale, thrips, and whiteflies.
Green lacewing eggs provide the best value among the beneficial insects that ARBICO offers. Once hatched, the larvae are voracious predators used to control a wide range of soft-bodied pest insects. Green lacewing are ideal for building a sustainable population within your growing area for continued control. Lacewings are preferred to ladybugs in many climates due to their ability to survive a larger temperature and humidity range while controlling many of the same pests.
Optimal Temperatures: 67-90°F, RH >30%
Life Cycle & Behavior: Lacewing eggs hatch within 3-10 days of receipt depending on temperature and humidity in the release area. Once hatched, lacewing larvae feed for 2-3 weeks on a variety of soft-bodied insects. Larvae are recognizable by their prominent mandibles (mouthparts), alligator-like appearance and pale coloration with dark markings. The larvae molt as they grow and mature through 3 instar stages. Pupation occurs in silken cocoons on the undersides of leaves or under loose bark. Green lacewing will overwinter in the pupal stage in cooler climates. Adults emerge from the cocoons with large veined ("lacy") wings ready to mate and lay more eggs. Adult green lacewings feed on pollen, nectar and honeydew while aiding in pollination. The complete life cycle lasts roughly 30 days.
Release Rates: For best results, release Green Lacewing early in the season when pest numbers are low. Make a minimum of three releases.
Orders of more than 250,000 may require seven days to fulfill.
- In gardens and greenhouses, release eggs at approximately 1,000 eggs per 2,000 sq. ft.
- For single shipments of less than 5,000 eggs, please call 1-800-827-2847
- For farms release 5,000 to 50,000 per acre depending upon infestation.
PLEASE NOTE: Ants and aphids have a symbiotic relationship. This is due to the fact that ants value the secretions of the aphids (honeydew) as a food source. The ants aggressively protect the aphids from other insect threats and the aphids produce the honeydew they crave. For this reason, before you begin any treatment to control aphids with predatory insects you will need to eradicate the ants in the area to be treated. Otherwise, they will wipe out any beneficials you introduce.
This Product Controls These Pests or Diseases: Alfalfa Weevil (Hypera postica Gyllenhal), Aphids (Mult), Armyworm (Pseudaletia unipuncta), Asparagus Beetles (Crioceris asparagi (common); Crioceris duodecimpunctata (spotted)), Bean Beetles - Mexican Bean Beetle (Epilachna varivestis Mulsant), Bean Thrips (Caliothrips fasciatus), Beet Armyworm (Spodoptera exigua (Hubner)), Beet Leafhopper (Circulifer tenellus), Black Scale (Saissetia oleae), Brown Almond Mite (Bryobia rubrioculus), California Laurel Aphid (Euthoracaphis umbellulariae), Caterpillar Eggs (Mult), Citrus Red Scale (aka California Red Scale) (Aonidiella aurantii), Citrus Yellow Scale (aka California Yellow Scale) (Aonidiella citrina), Coconut Mealybug (Nipaecoccus nipae), Colorado Potato Beetle (Leptinotarsa decemlineata), Grape Leafhopper (Erythroneura elegantula), Greenhouse whitefly (Trialeurodes vaporariorum), Leafhopper (Empoasca sp), Mealybug (Pseudococcus sp), Mexican Bean Beetle (Epilachna varivestis Mulsant), Mites (Tetranychus sp), Oleander Scale (Phenacaspis sp), Potato Leafhopper (Empoasca fabae), Potato Leafhopper; Bean Jassid (Empoasca fabae), Psyllids (Mult), Scale (Mult.), Silverleaf whitefly (Bemisia sp), Spider Mite (Mult), Sweet Potato Whitefly (Bemisia tabaci), Thrips (Franklinothrips sp), Tobacco budworm (Heliothis virescens), Two-Spotted Spider Mite (Tetranychus urticae)
Mist down plants lightly before releasing green lacewing. Gently shake the vial containing the lacewing eggs and bran. Tap contents out onto foliage. Distribute as evenly as possible throughout the affected area. If you have noticed ants in the growing area or nearby pest populations (mainly aphids and scale) you may want to hang a Dixie cup or paper coffee filter with a small amount of lacewing eggs within the plant canopy. This will keep the eggs separate from the ants and ensure predation does not occur.
What Should I Expect After Release?
Green lacewing eggs will hatch within 3-10 days of receipt. Lacewing larvae are difficult to spot once hatched out and camouflage well with their surroundings. You can inspect eggs for hatching by looking for color changes. If eggs are still green, lacewing larvae are still developing. If eggs are gray, the larvae have hatched out.
Keep in mind that beneficial insects work at a slower pace than chemical controls. If immediate knockdown or control of an insect population is necessary, consider spraying a fast-acting insecticide or select a more targeted predator/parasite.
Adults lay eggs near larval food sources, so adult activity will be higher in those areas. They will appear around one month after release of the eggs and tend to disperse if food sources are limited. Providing plants that bloom and pollinate at different times of the year helps cultivate a habitat suitable and attractive to the adult green lacewings.

Green Lacewings work very well against desert spider mites

Owner Response: Hi James,
This is a common issue. Green lacewing larvae are VERY small and difficult to find once released. We often recommend monitoring the eggs while still in the container and wait until you begin to see hatching before releasing. Please contact firstname.lastname@example.org to discuss more.
Excellent for white flies

Did not work
Jul 8, 2020 | By Elise Bozzuto
Owner Response: We are sorry you did not have good results releasing the lacewing eggs. While you can have success with a single shipment, generally followup releases will be needed for prolonged control or to build a population. We recommend a minimum of three releases for general pest control. More information about doing so can be found on the Instructions tab.

Didn't see a single one
May 3, 2020 | By Joseph
Owner Response: The lacewing larvae can be difficult to spot once hatched as they are small and well camouflaged. Something that may be helpful is going to the growing area at dusk or evening with a black light to look for the larvae. The lighter bands on the lacewing larvae will stand out against the plant matter.

Owner Response: Hi Richard,
Your first release of lacewings should be reaching adulthood anytime now since you are about 3 weeks down the line. Keep an eye out around dusk when they're most active!

Green lacewing eggs
May 31, 2018 | By Keith george
Owner Response: I am sorry to hear that you have not had the results you expected. It is generally helpful to repeat releases of the eggs 2-3 times at a weekly interval. That will stagger the life stages in the growing area and help build a population that is self-sustaining. Also, try using a black light to look for the larvae in the evening. The lightly colored parts of their bodies will stand out against the foliage.
